Description

Technical Field

[0001] This utility model relates to the technical field of maintenance equipment for blast furnace smelting disc-type water slag gas lifting wells, and in particular to a slag cleaning device for disc-type water slag gas lifting wells. Background Technology

[0002] In the blast furnace disc process for slag removal, the air-lift well is a crucial component of the slag system. Its main function is to use compressed air from the air-lift inlet to lift the slag-water mixture within the well to the separator; the air-lift well reaches a depth of 14 meters. However, due to water quality and slag caking, caking occurs on the top and walls of the air-lift well, negatively impacting production. Therefore, regular cleaning and maintenance of the air-lift well are necessary. Currently, conventional methods for cleaning air-lift wells have several problems: Scaffolding method: After draining the water from the air-lift well and lowering the internal temperature to 35°C, workers descend to the bottom to erect a full-span scaffolding and construction platform before cleaning layer by layer. This method not only takes up to four days to erect and dismantle the platform, extending the construction period and increasing costs, but also poses significant safety risks to workers working in the well. Cage method: Maintenance personnel are sent to the bottom of the well using a cage, but the cage's stability is poor and it cannot fit tightly into the shaft's inner diameter, making effective cleaning difficult. High-pressure water jet cleaning method: Using a high-pressure water jet can only clean the surface slag in the gas lift well, but cannot completely remove the hardened material, and cannot fundamentally solve the problem of material accumulation. Utility Model Content

[0003] The purpose of this invention is to provide a disc-type water slag gas lift well cleaning device to solve the problems existing in the prior art. It has a simple structure, is easy to use, effectively improves the cleaning effect, and effectively ensures the safety of the operation process.

[0004] To achieve the above objectives, this utility model provides the following solution:

[0005] This utility model provides a disc-type water slag gas lift well cleaning device, comprising: a liquid level regulating mechanism, a floating support mechanism, a fall prevention mechanism, and a chiseling mechanism. The liquid level regulating mechanism is connected to the gas lift well and can replenish water to the gas lift well to increase the liquid level inside the well, and can also discharge water from the gas lift well to decrease the liquid level inside the well. The top surface of the floating support mechanism is an operating surface for the operator to stand on. The floating support mechanism floats on the liquid surface inside the gas lift well and changes with the liquid level inside the well. One end of the fall prevention mechanism is detachably fixed to the top of the gas lift well, and the other end is worn by the operator. The chiseling mechanism is used by the operator to remove the hardened material accumulated on the inner wall of the gas lift well.

One end of the water replenishment pipe is connected to the slag and water discharge pool, and the other end is connected to the gas lift well. The fluid conveying device is located in the drainage pipe and the water replenishment pipe to provide power for the liquid flow in the drainage pipe and the water replenishment pipe.

[0007] Preferably, the fluid conveying device is a pneumatic lift or a water pump.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] The purpose of this invention is to provide a disc-type water slag gas lift well cleaning device to solve the problems existing in the prior art. It has a simple structure, is easy to use, effectively improves the cleaning effect, and effectively ensures the safety of the operation process.

[0022] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0023] This embodiment provides a disc-based water slag gas lift well cleaning device, such as... Figure 1 As shown, the gas lift well has a passageway at its bottom. It includes a liquid level regulating mechanism, a floating support mechanism, a fall prevention mechanism, and a chisel mechanism. The liquid level regulating mechanism is connected to the gas lift well and can replenish water to raise the liquid level inside the well, and can also drain water to lower the liquid level. The top surface of the floating support mechanism serves as an operating surface for the operator to stand on. The floating support mechanism floats on the liquid surface inside the gas lift well and changes with the liquid level. One end of the fall prevention mechanism is detachably fixed to the top of the gas lift well, and the other end is worn by the operator. The chisel mechanism allows the operator to remove the hardened material from the inner wall of the gas lift well. By setting up the liquid level regulating mechanism, the liquid level inside the gas lift well can be flexibly adjusted, creating a suitable liquid environment for slag removal work. Different liquid levels facilitate slag removal operations at different stages. The floating support mechanism floats with changes in the liquid level, ensuring operators always have a stable standing surface. This surface can adaptively adjust with the liquid level, guaranteeing both convenience and safety. The fall arrestor effectively prevents operators from falling and injuring themselves in case of accidental falls, improving safety when working at and around the top of the gas lift well. The chipping mechanism enables operators to effectively clean the sludge buildup on the inner wall of the gas lift well, promptly eliminating its impact on normal operation and restoring the well to its normal performance.

[0024] In a preferred embodiment, the liquid level regulating mechanism includes a slag and water discharge tank, a drainage pipe, a water replenishment pipe, and a fluid conveying device. The slag and water discharge tank is located outside the gas lift well. One end of the drainage pipe is connected to the slag and water discharge tank, and the other end is connected to the bottom of the gas lift well. One end of the water replenishment pipe is connected to the slag and water discharge tank, and the other end is connected to the gas lift well. The fluid conveying device is installed in the drainage pipe and the water replenishment pipe to provide power for the liquid flow within them. This liquid level regulating mechanism can form an efficient and closed liquid circulation system, ensuring smooth replenishment and drainage of the gas lift well. The slag and water discharge tank serves as a centralized treatment point, facilitating subsequent treatment of the discharged slag and water. The fluid conveying device precisely controls the flow rate and rate of drainage and replenishment, ensuring a stable liquid level within the gas lift well that can be flexibly adjusted according to actual needs. Different slag removal stages may require different liquid levels, and this structure can quickly respond to adjustment demands. Simultaneously, the pipe connection method ensures the sealing of the liquid level regulating system, preventing liquid leakage and reducing pollution to the surrounding environment and corrosion of equipment.

[0025] In a preferred embodiment, the fluid transport device is a pneumatic lift or a water pump. Choosing a pneumatic lift or water pump enhances the applicability of the liquid level regulation mechanism. Pneumatic lifts have the advantages of simple structure and no rotating parts, making them less prone to failure and reducing maintenance costs. They are suitable for situations requiring high equipment reliability, limited maintenance conditions, and liquids that may contain impurities. Water pumps, on the other hand, offer advantages such as large flow rates and stable pressure, making them more suitable for scenarios requiring rapid transport of large quantities of liquid and rapid liquid level adjustment. This provides users or operators with options, allowing for flexible configuration based on specific gas lift well conditions, cost budgets, ease of maintenance, and other factors, better meeting the diverse needs of actual slag removal operations.

[0026] In a preferred embodiment, the floating support mechanism includes multiple floating components and a working platform. Each floating component is detachably and fixedly connected to the underside of the working platform, which provides a standing platform for the operator. The use of multiple detachably connected floating components to support the working platform improves the assembly flexibility and stability of the entire floating support mechanism. The detachable structure facilitates transportation and storage; when not in use, the floating components and working platform can be disassembled and stored, saving space. When needed, it can be quickly assembled, improving work efficiency. Multiple floating components distribute the weight of the operator and tools across the working platform, making the platform more stable on the liquid surface, preventing the risk of capsizing, and providing a safer and more reliable operating environment for the operator. Furthermore, if a floating component is damaged, it can be replaced individually, reducing maintenance costs and difficulty.

[0027] In a preferred embodiment, the floating element is an inflatable tire, and the working platform is constructed from wooden planks spliced ​​together and laid on top of each inflatable tire. The inflatable tire, acting as a floating element, possesses good elasticity and buoyancy, adapting to different liquid surface fluctuations, reducing platform sway, and improving operator stability. Inflatable tires are lightweight, easy to transport and install, relatively low in cost from an economic perspective, and readily available and replaceable. The working platform constructed from wooden planks has a certain degree of elasticity, alleviating operator fatigue from prolonged standing. Simultaneously, the wood material is non-slip and soft, enhancing operational comfort. Furthermore, the modular design allows for flexible adjustment of the platform's size and shape according to the dimensions of the gas lift well and actual usage requirements.

[0028] In a preferred embodiment, an anti-slip mat is also included, which is laid and fixed to the top surface of the wooden scaffolding. The anti-slip mat significantly improves the safety of operators walking and working on the wooden scaffolding. The working environment inside the gas lift well is humid, and the wooden scaffolding is prone to water stains. Without an anti-slip mat, operators are highly susceptible to slipping and falling. The anti-slip mat effectively reduces the risk of slipping, ensuring the personal safety of operators during the slag removal process, allowing them to focus more on the slag removal operation and improving work efficiency.

[0029] In a preferred embodiment, the fall arrestor is a speed-differential fall arrestor. One end of the speed-differential fall arrestor is detachably and fixedly connected to the top of the gas lift well, while the other end is worn by the operator. The speed-differential fall arrestor features rapid braking; when the operator suddenly falls, it responds quickly, locking the rope in a very short time, limiting the operator's fall distance, and effectively reducing injury from the fall. The detachable connection facilitates quick installation and removal in different gas lift wells or different operating scenarios, improving the equipment's reusability. It is convenient for operators to wear and does not significantly affect the flexibility of their normal slag removal operations. By using the speed-differential fall arrestor, safety during operations is enhanced, providing operators with a sense of psychological security, allowing them to perform slag removal tasks with greater peace of mind.

[0030] In a preferred embodiment, a life vest is also included. The life vest, worn by the operator, serves as an additional safety measure, further enhancing the safety of the operator working within the gas lift well. In the event of an accidental fall into the liquid, the life vest provides sufficient buoyancy to keep the operator afloat, preventing drowning. Even if the fall arrest mechanism fails or other unforeseen circumstances cause the operator to fall into the water, the life vest provides maximum protection for the operator's life. This is of great significance for ensuring the personal safety of operators and reducing accident losses, while also giving operators greater peace of mind during operations.

[0031] In a preferred embodiment, the chipping mechanism is a pneumatic pick. As a chipping mechanism, the pneumatic pick possesses powerful impact force and crushing ability, enabling efficient removal of hardened material deposits from the inner wall of the gas lift well. The material deposits inside the gas lift well have undergone long-term deposition and solidification, resulting in high hardness that is difficult to clean with ordinary tools. The powerful performance of the pneumatic pick easily addresses this problem, quickly breaking up the hardened material and significantly improving the efficiency of the cleaning process. The pneumatic pick is relatively flexible to operate, allowing operators to easily control its working position and force, precisely cleaning material in different locations to ensure that material deposits in every corner of the gas lift well's inner wall are effectively removed, restoring the gas lift well's normal flow performance.

[0032] In a preferred embodiment, the disc-type water slag gas lift well cleaning device also includes a steel ladder. The top of the steel ladder is detachably and fixedly connected to the top of the gas lift well, providing operators with a convenient access route to and from the gas lift well. There is a certain height difference between the gas lift well opening and the ground or other operating surfaces. Without a ladder, it would be inconvenient for operators to move up and down, and there would be safety hazards. The steel ladder allows operators to safely and smoothly enter and exit the gas lift well, improving work efficiency. The detachable design facilitates installation and disassembly. When the gas lift well does not require cleaning operations or requires other maintenance work, the steel ladder can be removed, avoiding interference with other operations. Furthermore, the steel ladder is made of a sturdy and durable material, capable of supporting the weight of the operators and their tools and equipment, ensuring the reliability and stability of the access route.

[0033] The operating method of this disc-type water slag gas lift well cleaning device is as follows:

[0034] Preparation

[0035] Equipment Inspection: Water temperature is below 35℃, oxygen content is within acceptable limits. Conduct a comprehensive inspection of all components of the sludge removal device, ensuring there are no leaks in the sludge discharge tank of the liquid level regulation mechanism, and that the drainage and water supply pipes are tightly connected and free of blockages. Check that the fluid conveying equipment (pneumatic lift or water pump) is operating normally. Confirm that the inflatable tires of the floating support mechanism are fully inflated (they need to be covered with cloth bags to prevent punctures or leaks), that the wooden planks are securely spliced, and that a non-slip mat is laid on the top surface. Check that the differential fall arrestor and life jackets are functioning properly, that all components of the pneumatic drill are properly connected, and that the steel ladder is securely installed.

[0036] Connection equipment: Connect one end of the drainage pipe to the slag and water discharge pool and the other end to the bottom of the air lift well; connect one end of the water supply pipe to the slag and water discharge pool and the other end to the air lift well; detachably and securely connect one end of the speed difference fall arrestor to the top of the air lift well; detachably and securely connect the top of the steel ladder to the top of the air lift well.

[0037] Personnel protection: Operators should wear protective equipment such as speed difference fall arrestors and life jackets.

[0038] Adjusting the liquid level in gas lift wells

[0039] Depending on the different stages of the slag removal operation, a liquid level regulating mechanism is used to adjust the liquid level in the gas lift well:

[0040] Water replenishment operation: Turn on the fluid conveying equipment (pneumatic lift or water pump) and transport the liquid in the slag and water discharge pool to the air lift well through the water replenishment pipeline, so that the liquid level in the air lift well rises to a suitable height.

[0041] Drainage operation: If it is necessary to lower the liquid level in the gas lift well, start the fluid transport equipment to change the flow direction or start a special drainage process to discharge the water in the gas lift well to the slag and water discharge pool through the drainage pipe.

[0042] Build an operating platform

[0043] Operators enter the gas lift well via a steel ladder and place the floating support mechanism on the liquid surface, allowing it to float naturally. The floating support mechanism adaptively adjusts to changes in the liquid level, providing operators with a stable standing surface.

[0044] Slag removal operation

[0045] Operator in position: The operator stands on the wooden ramp of the floating support mechanism and puts the other end of the speed difference fall arrestor on his body to ensure adequate protection.

[0046] Slag removal operation: Operators use pneumatic picks to chisel and clean the hardened material accumulated on the inner wall of the gas lift well. Because pneumatic picks are relatively flexible, the working position and force can be precisely controlled according to the location and hardness of the accumulated material, effectively removing the accumulated material from every corner.

[0047] Homework finished

[0048] Cleaning and Reset: After the slag removal work is completed, shut down the fluid conveying equipment and stop the operation of the liquid level regulating mechanism. Remove the floating support mechanism from the gas lift well, clean and inspect it. If any parts such as the pneumatic tires are found to be damaged, mark them or replace them. Clean and maintain tools such as pneumatic picks for future use.

[0049] Equipment removal: Disassemble the steel ladder and liquid level adjustment mechanism connecting parts and other detachable structures, and properly store the relevant devices.

[0050] Personnel evacuation: Operators safely left the gas lift well via a steel ladder.
